Abstract

The J(c) of a sintered Bi-2223/Ag multi-layered bulk sample increases as the number of Ag layers is increased. The sample used in this experiment wasplaced next to the bifilarly wound coil consisting of two coils having thesame properties located at the same place. With the sample fixed, a current was applied to the two coils in the same and then in the opposite direction so as the fluxes augment or counteract each other, and the difference inthe synthetic impedance of the two coils (DeltaZ) was measured. First, thetemperature dependence of DeltaZ for Ag and Bi-2223 samples, and Bi-2223/Ag multi-layered sample pellets were measured at 10 kHz. Next, each sample was treated as a serial circuit having the same resistance and inductance. and a formula for obtaining DeltaZ for each bifilarly wound coil was derived. The calculated values of the temperature dependence of DeltaZ obtained bysubstituting the sample and coil constants into the formula corresponded fairly well with the measured ones.
